80Instruments and controlsFuel gauge
Displays fuel level in the tank.
Control indicator Y also illuminates in
instrument cluster 3 81 when fuel
level is low (range of approx.
30 miles): refuel immediately 3 132.
Never run the tank dry.
Diesel fuel system, bleeding 3 144.
Notice
To ensure the fuel level is displayed
correctly, the ignition must be
switched off before refuelling. Avoid
minor fuel top-ups (e.g. less than
5 litres) to ensure accurate readings.
Because of the fuel remaining in the
tank, the top-up quantity may be less
than the specified tank capacity.
Fuel economy gauge
The fuel economy gauge provides an
instantaneous calculation of fuel
efficiency based on current driving style.
The gauge uses colours to indicatecurrent fuel efficiency:Green=best fuel economy
is being achievedYellow=driving style too
aggressiveOrange=least efficient fuel
economy
The fuel economy gauge is enabled by default. It can be disabled via the
Infotainment system. Refer to
Infotainment system manual for
further information.
Service display
When the ignition is switched on, the
remaining distance before the next
service is due may be shown briefly in the Driver Information Centre. Based
on driving conditions, the interval at
which a service will be indicated can
vary considerably.
The distance before service display
can also be shown by pressing button on end of wiper lever for approx.
5 seconds.

Puncture
A puncture or severely under-inflated
tyre is indicated by illumination of
control indicator w together with C
3 84 and a corresponding message
appears in the Driver Information
Centre. Stop vehicle and switch off
engine.
Tyre pressure 3 190, Tyre repair kit
3 161, Spare wheel 3 165, Wheel
changing 3 164.
Temperature dependency Tyre pressure depends on the
temperature of the tyre. During
driving, tyre temperature and
pressure increase.
The tyre pressure value displayed in
the Driver Information Centre shows
the actual tyre pressure. Therefore it
is important to check tyre pressure
with cold tyres.Relearn function
After changing the wheels, TPMS
needs to recalculate.
With the vehicle stationary, select the tyre pressure menu in the Driver
Information Centre by pressing button
on end of wiper lever. Press and hold button for approx. 3 seconds to
initialise recalculation. A
corresponding message appears in
the Driver Information Centre.
Several minutes of driving may be
required to complete the relearn
process.
If problems occur during the relearn
process, control indicator w remains
illuminated and a warning message is displayed in the Driver Information
Centre.

General information
The use of commercially available
liquid tyre repair kits can impair the
function of the system. Factory-
approved tyre repair kits can be used.
Tyre repair kit 3 161.
External high-power radio equipment
could disrupt the tyre pressure
monitoring system.
Each time the tyres are replaced,
TPMS sensors must be dismounted
and serviced by a workshop.
Tread depth
Check tread depth at regular
intervals.
Tyres should be replaced for safety
reasons at a tread depth of 2-3 mm
(4 mm for winter tyres).

Service information In order to ensure economical and
safe vehicle operation and to
maintain the value of your vehicle, it
is of vital importance that all
maintenance work is carried out at the proper intervals as specified.
The detailed, up-to-date service
schedule for the vehicle is available at
the workshop.
Service display 3 80.
Engine identification 3 177.
European service intervals
Maintenance of your vehicle is
required every 25,000 miles or after
2 years, whichever occurs first,
unless otherwise indicated by the
service display.
A shorter service interval can be valid for severe driving behaviour, e.g. for
taxis and police vehicles.Confirmations
Confirmation of service is recorded in the Service and Warranty Booklet.
The date and mileage is completed
with the stamp and signature of the
servicing workshop.
Make sure that the Service and
Warranty Booklet is completed
correctly as continuous proof of
service is essential if any warranty or
goodwill claims are to be met, and is
also a benefit when selling the
vehicle.
Service display
The service interval is based on
several parameters depending on
usage.
The service display, located in the
Driver Information Centre, indicates
when the next service is due. Seek
the assistance of a workshop.

protection down to approx. -28 °C.
This concentration should be
maintained all year round. The use of additional coolant additives that
intend to give additional corrosion
protection or seal against minor leaks
can cause function problems. Liability
for consequences resulting from the
use of additional coolant additives will be rejected.
Brake fluid Over time, brake fluid absorbs
moisture which will reduce braking
effectiveness. The brake fluid should
therefore be replaced at the specified interval.
